Nest thermostat

You can get the Nest Learning thermostat for £99 with the new Npower tariff

Npower has teamed up with Nest to offer a deal that includes a new online fixed energy tariff and a Nest Learning thermostat at a reduced price. 

Npower is offering a Nest Learning thermostat for a reduced price of £99, including installation, if people sign up to its new online duel fuel tariff, the Intelligent Fix - April 2017.

Paiing by direct debit, the tariff would cost customers around £1,217 a year (based on Ofgem's standard medium consumption figures), and the price would be fixed until 30 April 2017. 

The Nest thermostat aims to regulate the heat in your home without you having to schedule it, as you would with normal heating controls. It also has wireless capabilities, so you can turn your heating down or up when away from your home, hopefully saving you money.

We haven't looked at the Nest yet, but we recently reviewed the Hive thermostat, a similar device - find out how it works and if we thought the Hive was worth buying.

Pros and cons of fixed energy tariffs

There are advantages and disadvantages to choosing a fixed energy tariff. On the plus side, you know exactly how much your energy will cost per unit for the duration of your deal, and won't be affected by price increases. 

A downside of fixed energy tariffs can be that you will sometimes end up paying more for your energy than those on variable packages (although this is less often the case now than it used to be). You also won’t benefit if energy prices drop. 

It's worth noting that there is a £50 exit fee for each fuel type if you do need to leave the tariff, which is quite high for an exit fee, so it's worth taking this into account.
